Will do!

Hi folks, I made a post a few weeks ago on trying to work out why my server kept randomly dropping off the network, making all GUI, SSH and VM/Docker instances unresponsive. I eventually boiled it down to something funky going on with my Plex docker. I moved that to a VM and it's been stable ever since (uptime of about 13 days) - however around 8 hours ago (according to the end of the syslog) the server became unresponsive again. Before I descend back down to the pits of despair I just managed to hoist myself out of, does my most recent syslog seem to suggest anything glaringly wrong? I'd look myself, but I really don't know what I'm looking for. Bad RAM? Power issue? Dying drive? Any help would be greatly appreciated. Thanks! syslog

Seems to have "fixed" it - no idea what issue the VM had, and I don't know how to troubleshoot it but for now moving Plex to a VM seems to make the system stable again. Unfortunate downside is running the overhead of an OS for one program, but I'd rather have my server running! Hardware is a 9600K, 48GB of RAM, 20TB across 8 disks (I know, I'm working on it).

Migrated to a Windows VM yesterday (I know Windows isn't a great choice for a "server" VM, but I really can't be bothered to argue with Linux while I need my Plex server back up ASAP), and so far so good - unRAID has been stable. Time will tell if it remains this way, but at the moment it looks like something to do with the Plex Docker container/configuration.

Mm, definitely something up with Plex. Can't tell if it's the Docker itself or something load-related when Plex starts doing some heavy lifting.

Makes sense. Although interestingly, I've had the Plex docker spun down since last night, and no signs of issues so far... I may migrate this to a VM and see if this is still remains stable. Wonder what Docker could theoretically do to affect the stability of the entire system?

Interesting - would it be worth running memtest? I have 2x8GB and 2x16GB sticks in at the moment, does unRAID not like weird configurations?

Is that 6.12.3? That's what I'm running now, so sadly might not be my issue. I've stopped the Plex docker for now, see if that makes any difference in stability.

Something else I've just noticed - I was doing some transcoding through Plex (nothing big, 1080 to 1080) and the server went down in a matter of minutes after being up. Is there anything in the logs to suggest that Plex might be the issue? It's currently running in a Docker container.

I can't even access my HA VM, I lose access to everything. Mine definitely started before the latest update, and happened again a few months ago which I seemed to fix by updating the OS.

Do you want the syslog file itself? I had the server running already, and this is the most recent one. It was last modified just after I rebooted it after it's most recent crash, which I assume was at 13:37 today as that's when the log finishes. Appreciate any help. syslog

Oh, and here's the diagnostics file from what I assume was before the most recent crash (earlier last night, as I realised the server was down this morning). viki-diagnostics-20230316-1915.zip

Hi folks, I know, another "why is my system crashing post", sorry... I'm having this issue where my system seems like it crashes, but I'm not sure how to verify this as the CLI stops outputting after the suspected crashes. After a day or so my dockers and VMs stop and I cannot access the Web UI. I also can't ping the server in the local network. All things considered, it seems like a crash and I have to hard shutdown to get the server responsive again, where it will crash again after a day or so. This happened a while ago, and I seemed to fix it by either disabling c-states and updating unRAID. Alas, I don't know what else I can do now the issue has come back. There's been no hardware changes, temps seem fine and I haven't changed anything massive software wise other than updating unRAID to 6.12.3 and deleting unused Appdata folders from dockers I don't use anymore. Any advice would be hugely appreciated, any data further than this diagnostics file just ask. Thanks! viki-diagnostics-20230731-1757.zip
